       ISSI ANNOUNCES SELECTED FINANCIAL RESULTS FOR FISCAL FOURTH QUARTER

         Santa Clara, Calif.--October 31, 2006--Integrated Silicon Solution,
Inc. (Nasdaq: ISSI) today reported selected financial results for the fourth
fiscal quarter ended September 30, 2006.

         Revenue in the fourth fiscal quarter ending September 30, 2006 was
$59.0 million, compared with $54.7 million in the June 2006 quarter and $61.5
million in the September 2005 quarter. This represents a sequential increase of
7.9% from the June 2006 quarter.

         The Company's cash, cash equivalents and short-term investments totaled
$113.3 million at September 30, 2006 which was a decline of $3.8 million from
June 30, 2006. Additionally, the Company's short-term debt was $1.6 million at
the end of the September 2006 quarter which was a decline of $7.2 million from
the end of the June 2006 quarter.

         The Company's inventory at September 30, 2006 totaled $52.4 million
which was a decline of $1.8 million from June 30, 2006.

         "We saw solid growth this quarter as revenue grew 7.9% from the
previous quarter," said Jimmy Lee, ISSI's Chairman and CEO. "This growth was
driven by a combination of stable pricing and seasonally strong SRAM and DRAM
demand. Additionally, our cash position, net of debt, grew quarter to quarter,
and we continued to show progress in our inventory management."

         Due to the continuing internal investigation of its past stock option
granting practices by the Special Committee of the Board of Directors, the
Company is not providing detailed GAAP or Non-GAAP financial information for the
fiscal quarter or year ended September 30, 2006. The Company intends to issue
full results for the fiscal year ended September 30, 2006, and to file its
Annual Report on Form 10-K for that period, together with any restated
historical financial statements, as soon as practicable after completion of the
Special Committee review.
